Variation 5 :
Part 1 :
voice ní 1 (low) : from bar 1 to B of bar 8, volume = 100%; from A of bar 8 to bar 10, volume = 80%; from bar 11 to the end, volume = 100%.
voice ní 2 (high) : from bar 1 to bar 8, volume = 80%; from bar 9 to the end, volume = 100%.
Part 2 :
voice ní 1 (low) : from bar 1 to bar 8, volume = 80%; from bar 9 to the end, volume = 100%.
voice ní 2 (high) : from bar 1 to bar 8, volume = 100%; from bar 9 to 5th note (E) of the bar 12, volume = 80%, then to the end, volume = 100%.
The whole piece, speed = 65%, staccato = 100%.
Variation 7 (al tempo di Giga) :
The two voices : volume = 100%, staccato = 100% (in part 2, voice 2, bar 3, stacatto = 75% from 7th to 11th note).
The whole piece, speed = 45%.
Variation 10 (Fughetta) :
Part 1, first time : volume = 100%, staccato = 100 %.
repeat : volume = 80%, staccato = 50 %.
Part 2, first time : volume = 100%, staccato = 100%.
repeat : from bar 1 to bar 12, volume = 80%, staccato = 50 %, then from bar 13 to the end,
volume = 100%, staccato = 100 %.
The whole piece, speed = 55%.
(About this particular piece, I know that I have used some unorthodox ornaments. The reason is not that I am not concerned with the style, but the fact is that the most important thing for me is the acoustical result I want to obtain. If I believe that the music will sound better (have a better "acoustic image", if I can say) with an or several unorthodox ornaments, so I use unorthodox ornaments. In fact, I am not a "baroque-orthodoxy-bigot" !!!)
Variation 14 :
Part 1 :
voice ní 1 (low) : from bar 1 to G of bar 9, volume = 80%; bar 14, volume = 80% (the rest, volume = 100%).
voice ní 2 (high) : volume = 100% except for bar 13, volume = 80%.
Part 2 :
voice ní 1 (low) : volume = 100% except bar 13, volume = 80%.
voice ní 2 (high) : from bar 1 to E of bar 9, volume = 80%; bar 14, volume = 80% (the rest, volume = 100%).
